RAIL-CONNECTING CHAIR-PLATE PATTERN.

Specification of Letters Patent.

Application filed August 27, 1920. Serial No. 406,324.

. T all whom it may concern:

Be it known that I, CHARLES J. SHinLns, a citizen of the United Statesof America, residing at Columbus, in the county of Franklin and State ofOhio, have invented certain new and useful Improvements inRail-Connecting Chair-Plate Patterns, of

V in alinement.

which the following is a specification.

My present invention relates generally to rail connecting chair plates,and more particularly to the manufacture ofchair plates for use inspanning the joints between, and connecting in stepped relation, theadjacent ends of'rails of different sizes, that is different heights,widths and thicknesses.

It is well known that but a simple matter is presented in the formationand utilization of patterns for casting chair plates to be used in theconnection of rails of similar' sizes, but dissimilar rails present amuch different, more complicated, expensive and,

troublesome situation as the rail chairs must properly fit the rails sothat the latter are joined in stepped relation as to their basesandoffset relation as to their Webs, with the inner sideand topfaces oftheir heads This latter situation at the present time requires a skilledpattern maker and usually a different and newly made pattern for eachdifferent type of connection encountered, and as the types ofconnections met with in practice are of widely varying natures, it isobvious that much difficulty and expense attends theordinarysolution ofthe matter.

It is to avoid the'necessity of making new patterns for castings foreach type of offset or stepped joint at the junction of rails ofdifferent sizes, as well as to avoid the necessity of the services of askilled pattern maker, that my invention proposes and has for its objectand construction whereby patterns may be formed by assembling standardsizes of rail end engaging sections with detachable interchangeableconnecting sections whose offsets will correspond to variou combinationsof end sections, and with base pieces whose stepped surfaces alsocorrespond thereto and to the, offset connecting sections and arelikewise detachable and in terchangeable.

In this way it will simply maintain at hand the standard nd sections ofvarious sizes together with offset connecting sections for variouscombinations of end be necessary to 7 sections, and base platescorresponding to the offset connecting sections, in order that a properpattern for a particular offset joint or rail junction may be readilyand quickly assembled without requiring any particular skill in thisoperation. In the accompanying drawings illustrat ing my invention, andwherein for the purpose of better illustration and more readyunderstanding I have shown mv improved adjustable pattern in connectionwith rail ends tob'e connected, similar to the manner in which chairplates cast from the patterns will be actually used,

Fig.- 3 is a horizontal section taken on 7 line 33 of F 1, but showingthe actual chair plates as formed from the pattern constituting myinvention, j

Figs. 4, 5 and 6 are vertical transverse sections taken respectively onlines 4-4l,o 55 and 6-6 of Fig. 1,

Fig. 7 is an innerside view of one of the patterns, V

' Fig. 8 is a top plan view thereof,

Fig. 9 is a vertical transverse section taken on line 9-9 of Fig. 3,

Fig. 10 is an enlarged inner side view of the connecting section of thepattern,

Fig. 11 is an end view thereof, and

Fig. 12 is a'top plan view thereof.

Referring now to these figures and particularly to Figs. 1' to 6inclusive, my invention proposes a pattern for use in forming chairplates 15 shown more especially in Figs. 3 and 9, which are properlyoffset at pointsintermediate their ends to properly connect rails 16 and17, of different sizes, and whose bases 18 and 19 and webs 20 and 21must be offset. the former vertically and the latter horizontally, inorder to bring the inner side and upper surfaces of the rail heads 22and 23 in alinement as particularly seen by reference to Figs. 1 and2.

The pattern as proposed by my invention and whose showing in Figs. 1, 2,4:, 5 and 6 at opposite sides of joint ends of the rails 16 and 17 isartificial, to the extent that the patterns are shown in these figuresin place of the chair plates casttherefromand actually utilized inpractice, embodies detachable end sections 24 and 25, formed separatefrom one another and in standard sizes to properly fit standard sizes ofrails. Each of these sections, as particularly shown in Figs. 4 and 6,has a body properly shaped and formed of wood as indicated at 26, whichis preferably bound with metal as at 2'? in order to prevent warping anddistortion under varying climatic conditions, as well as conditions ofuse, so that the necessity of re fitting from time to time is avoided.Each standard section 2th and 25 has a flange portion 28 with verticalopenings for the reception of screws 29, the latter of which serve todetachably connect the outer edges of the flanges upon the verticallyoffset or stepped surfaces 30 and 81 of the base plate 32 which forms apart of the pattern, it being understood that a variety of base plateswill be provided having their surfaces vertically spaced to properlyhold with the vertical spacing of the vertically of rail losses.

lVith the standard sections 2% and 25 thus secured upon the base plate32, the inner ends of these standard end sections, provided withvertical grooves 33 as shown in Fig. 12, are connected by offsetconnecting sections 34, preferably formed of wood and either bound orunbound, or formed of metal and further provided with vertical side ribs85 to extend into the grooves 33 of the end sections. These connectingsections 34 have endwise projecting threaded studs 36 adapted to extendinto socket portions at the inner ends of the end sections 24L and 25 asshown in Fig. 10 and to receive connecting nuts 37, so that the innerends of the end sections 2% and 25 will thus be rigidly connected intheir proper vertically and horizontally offset relation particularlyseen by a comparison of Figs. 7 and 8.

By the means oeseribed I am thus en abled to provide for the readyformation of patterns by simply keeping in stock standard endsections 2aand 25 and interchangeable base plates 32 and interchangeable coinnectingsections 3a to accord with various combinations of end sectionsof different sizes so that in use it becomes simply a matter ofmeasurement and selection of proper sections, the actual joining ofthese sections being obviously a simple operation which needs no skillas compared to that of a pat tern maker which the present practice ofmaking a single one-pie re pattern for each chair plate requires.

It furthermore becomes obvious that my invention thus does away to amaximum extent with the disadvantages, trouble and expense in properlyproviding for the connection of adjoining ends of railsof differentsizes, as well as delays incident to the making and fitting of newpatterns.

I claim: 1. A pattern for the casting of intermediately offset railconnecting chair plates, including end rail engaging sections ofstandard sizes to fit standard rails, and interchangeable intermediatesections forming connecting members for the end sections having oflsetsto correspond with particular sizes of end sections, as described.

2. A pattern for the casting of intermediately offset rail connectingchair plates, including end rail engaging sections of standard sizes tofit any rails, and interchangeable intermediate sections formingconnecting members for the end sections having offsets to correspondwith particular sizes of end sections, each of said end sectionsincluding a body portion having a binding to prevent warping anddistortion in use.

A pattern for the casting of intermediately offset rail connecting chairplates, including interchangeable end sections of standard sizes to fitall sizes of rails, a vertically and horizontally offset connectingmember detachably connecting the inner ends of said sections, and whoseofisets correspond to the dissimilar sizes of the end sec tions, and abase plate to which the end sections are detachably connected, havingvertically offset upper surfaces corresponding to the vertical offset ofthe connecting member as described.

, 4. A pattern for the casting of intermediately offset rail connectingchair plates, including interchangeable end sections of standardsizes'to lit various sizes of rails, a vertically and horizontallyoffset connecting member detachably connecting the inner ends of saidsections, and whose offsets correspond to the dissimilar sizes of theend sections, and a base plate, said end sections and said connectingsectionhaving relatively engaging ribs and recesses to maintain the samein proper alinement.

5. A pattern for the casting of interme diately offset rail connectingchair plates, including interchangeable end sections of standard sizesto fit all sizes of rails, a vertically and horizontally offsetconnecting member detachably connecting the inner ends of said sections,and whose offsets correspond to the dissimilar sizes of the endsections, and a base plate, said end sections and said connectingsection having relatively engaging ribs 'and recesses to maintain thesame in proper alinement, the connecting section also having endwiseprojecting threaded studs adapted to enter sockets of the end sections,and nuts engaging the studs to secure the end and connecting sectionstogether.
